Mix Fresh B4_Jx Telegram Stealer Log Leaked 7,853 Accounts

HEROIC analysts identified this stealer log on March 31, 2026. The breach exposed 7,853 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as the Mix Fresh B4_Jx stealer log.

Why This Is Dangerous

The Fresh designation in this log's name signals that the credentials were recently stolen at the time of distribution, meaning the passwords were likely still active and unchanged. Fresh credentials are significantly more valuable to attackers because they have not yet been flagged or reset by affected users.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of associated login pages spanning multiple services

Why This Matters

Fresh plaintext credentials tied directly to login URLs enable immediate account access. Reused passwords across email, banking, or retail accounts allow credential stuffing to extend the impact into account takeover, identity theft, and financial fraud well beyond the original compromise.

How This Stealer Log Works

Infostealer malware infiltrates a device through cracked software, pirated content, or malicious browser extensions, then extracts every saved browser password, autofill entry, and session cookie. Results are packaged into fresh log batches labeled with distribution codes like B4_Jx and shared on Telegram channels where criminals pick through them for high-value accounts.
